Search for: [Abstract = "ouble value of the pixel size. OSEM algorithm gives better outcomes for both the qualitative and quantitative assessment in comparison to FBP method. The choice of reconstruction parameters is the most important in assessment of small and middle\-size lesions. The choice of reconstruction parameters does not have influence on diagnostic assessment of large lesions. There is still limited number of publications which concern the optimization of iterative algorithms applied in reconstruction of SPECT images of GEP\-NET. There were most often phantom studies. However, the phantom studies cannot be used completely as the indicator in clinical practice. They might only determine the choice of reconstruction parameters. The results from phantom studies always require verification in clinical trials. The key to obtain answer if choice of reconstruction technique and its parameters is appropriate and most effective is always empirical study."]
